Method for distributing MPLS-TP service channel resources in OTN transmission equipment and device thereof

Abstract

The invention discloses a method for distributing MPLS-TP service channel resources in OTN transmission equipment and a device thereof. The OTN transmission equipment provides a plurality of MPLS-TP service data channel accesses. In the method comprises the following steps: (1) a network management system sets the service grades of the MPLS-TP service channels accessed in the OTN transmission equipment; (2), the OTN equipment carries out corresponding resource distribution among the accessed MPLS-TP service channels according to the set service grades; (3), the OTN equipment encodes and sends the service grades of the channels, and the OTN equipment on the receiving side performs corresponding encoding, and carries out resource distribution on the corresponding MPLS-TP service data channels according to the service grades. The invention provides the user grading service of the MPLS-TP service data, realizes high QoS capability, and is favorable for bearing and transmitting multi-channel MPLS-TP service data in OTN.

Description

technical field [0001] The invention belongs to the field of communication technology and transmission technology, in particular to an OTN (Optical Transport Network)-based MPLS-TP (MPLSTransport Profile) data service transmission technology. Background technique [0002] In recent years, with the rapid development of IP packet network applications, MPLS-TP and OTN, the technical representatives of PTN (Packet Transport Network), are the two major development directions of the optical transport network at the access layer and the core layer respectively. Combining adaptation and scheduling, and deploying at different network levels, PTN technology can be used to fine-tune management of customers and service flows, and OTN large-grained containers can be used for scheduling when large-capacity services are groomed. It meets the transmission requirements of TDM (Time Division Multiplexing: Time Division Multiplexing) services for synchronous clocks, effectively solves the IP-b...

AI Technical Summary

Problems solved by technology

[0004] However, this method of unified processing of Ethernet data cannot fully guarantee the QoS requirements for aggregation and transmission of MPLS-TP service data of several channels

Since the types of services transmitted by the MPLS-TP network include TDM, IP, and Ethernet, etc., if the OTN transmission equipment performs the same service channel establishment and bandwidth resource allocation, the transmission characteristics of different services cannot be fully utilized, making the use of equipment resources more efficient. Very low, business scheduling is not flexible, and it is difficult to meet the quality of service requirements of high-level business users (such as frame loss, delay, etc.)
